Answer:
1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).
2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.
3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.

Smoking during pregnancy affects your and your baby's health before, during, and after your baby is born. The nicotine (the addictive substance in cigarettes), carbon monoxide, lead, arsenic, and numerous other poisons you inhale from a cigarette are carried through your bloodstream and go directly to your baby. Smoking while pregnant will:
<span>Lower the amount of oxygen available to you and your growing babyIncrease your baby's heart rate<span>Increase the chances of miscarriage and stillbirth</span>Increase the risk that your baby is born prematurely and/or born with low birth weightIncrease your baby's risk of developing respiratory problems</span>
The more cigarettes you smoke per day, the greater your baby's chances of developing these and other health problems. There is no "safe" level of smoking for your baby's health.
C: primary Consumer
<em>primary consumers</em> are typically animals that eat plants aka herbivores.
<em>producers </em>would be plants
<em>secondary consumers </em>are typically ones that eat meat or eat meat and plants aka omnivores.
<em>decomposers, </em>I believe are like your fungus or anything that feeds off of dead organisms or eat the waste of that organism.
Hopefully this helped. I remember learning about this in college.
The addition of acetyl groups to histones is associated with chromatin condensation and and higher levels of gene expression
Answer: The complementary strand is TCC- GAT - TTG
Explanation: During DNA replication, each strand of the DNA serves as a template for the synthesis of a new strand, thereby producing two new DNA molecules, each with one new strand and one old strand. A template is a DNA strand that would allow nucleotide molecules to be lined up in a specific order and be joined to create another DNA with a unique sequence. This results in creation of a double stranded DNA in which each strand is complementary to the other. In nucleotide base pairing, Guanine pairs with Cytosine while Thymine pairs with Adenine.
G = C while T = A.
